Hi,
  I just tried on my xfree86 4.4.0 RC2 candidate linux box with Radeon 9200
with DRI enabled:

$ x11perf -getimagexy500
x11perf - X11 performance program, version 1.5
The XFree86 Project, Inc server version 40399902 on :0.0
from aquarius
Sat Jan 31 01:35:00 2004

Sync time adjustment is 0.0280 msecs.

      4 reps @ 2372.4955 msec (     0.4/sec): GetImage XY 500x500 square
      4 reps @ 2642.7983 msec (     0.4/sec): GetImage XY 500x500 square
      4 reps @ 2372.0420 msec (     0.4/sec): GetImage XY 500x500 square
      4 reps @ 2369.9855 msec (     0.4/sec): GetImage XY 500x500 square
      4 reps @ 2369.9825 msec (     0.4/sec): GetImage XY 500x500 square
     20 trep @ 2425.4608 msec (     0.4/sec): GetImage XY 500x500 square

My system was even slower, it more or less hung my X-windows for a while.
